Implement TotalDownload option.

Browse Source 
Setting this option will change the download progress to show the amount
downloaded, download rate, ETA, and download percent of the entire
download list rather than per each individual file.

The progress bar is still based on the completion of the current file
regardless if the TotalDownload option is set.

This closes FS#7205.
